So basically says he wants a guy who is tall, has arm strength (because it can't be improved much), has some experience under center, goes through progressions, doesn't want a running quarterback because they take a beating (unless they are special athlete ala Jackson).
If you take his words as his gospel, you eliminate: Mayfield-height, spread, Jackson-accuracy in pocket, Allen - accuracy, Rudolph - arm strength, spread.
It's really just Darnold and Rosen.
In the next tier the closest thing is probably Mike White. Falk, Laluetta have arm strength issues and things of that nature. White played under center, read full field progressions and has a big arm.
